measure of friction in bearings

[SolidCreative]

How can I tell a certain bearing will have lower friction then another bearing? Most manufactures dont list the coefficent of friction. Is that the value I should be looking for?

Thanks

What you are looking for is probably a torque value for each bearing under the same conditions. Look at the Dyna Roll site and you can get a feel for this bearing parameter.
If you look further into the site you will see that this value requires some special equipment for evaluation.

SolidCreative,

What kind of bearings are you asking about, and what do you plan to do with them?
